CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 450,238, dated April 14, 1891.

Application filed November 13, 1890- Serial No. 371,339- (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN E. KAUFFELT, a citizen of the United States, residing at Shrewsbury, in the county of York and State of Pennsylvania, have invented a new and useful Oar-Coupling Link, of which the following is a specification.

This invent-ion relates to car-couplings,and more especially to the links thereof; and the object of the same is to produce a link of this character, which will stand at the proper point to enter the inouth of an approaching drawhead.

To this end the invention consists of a carcoupling link constructed substantially as hereinafter more fully described and claimed, and as illustrated in the accompanying drawings, wherein- Figure 1 is a perspective view of my improved link. Fig. 2 is a section of a drawhead, showing my link supported therein with its point raised. Fig. 3 is a similar view with the point depressed. Fig. 4: is a plan view of the link, taken from the under side.

Referring to the said drawings, the letter D designates an ordinary draw-head, through which passes a coupling-pinP, and on this pin is mounted my improved link L, which is of the following shape: The link is of metal, with its body bent near its center at a slight angle A, one of its ends H being thickened to make it heavy and the other end being beveled or cut away, as at O, on its under side. The heavy end of the link is provided with an oval hole 0, whose longest diameter stands at right angles to the length of the link, and throughout the balance of the link is the usual slotted opening S, as best seen in Fig. at.

with alink of the above construction,when the heavy end is placed in the draw-head D and the pin P dropped through the oval hole 0 itwill be obvious that the lighter end of the link will be supported slightly above or below a horizontal plane. If the pin P fit loosely in the hole 0, the weight of the heavy end H over the mouth M of the'draw-head Will be sufficient to support the light end of the link; or, if the shortest diameter of the oval hole 0 be about the same as the diameter of the pin,it will be obvious that the link o will cramp on the pin sufficiently to prevent the rise and fall of its lighter end. The link' can of course turn about the pin, and the oval shape of the hole 0 permits it to twist slightly, as will be understood.

In Fig. 2 the link is shown with the angle A downward, thereby causing the iighter end to be slightly raised, whereas in Fig. 3 the angle Ais uppermost and the pointis slightly depressed. These positions are obviously asoo suined in order to guide the link into the approaching draw-head. The bevel 0, although 'shown on but one side, may exist on both, and

is obviously for the purpose of assisting the. free end of the link to enter the approaching draw-head.

What is claimed as new is 1. The herein-described car-coupling link having a slight angle in its body at about the center of its length, one end of said link being heavier than the other, as set forth.

2. The herein-described car-coupling link having a slight angle in its body at about the center of its length, one end of said link being heavier than the other, said heavy end being provided with an oval hole standing transversely of the link and the balance of the link with the usual slot, as hereinbefore set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two witnesses.

' JOHN E. KAUFFELT.
